Google is trading 12.79% lower at $283.33 after its third-quarter report missed revenue and earnings expectations. - Reuters reported negative free cash flow of $9.07 billion, driven by AI research and infrastructure spending. - Search advertising also fell short of estimates, alongside concerns about returns on AI investment. - The broader market is weaker, but the earnings news directly explains the sell-off; the decline is much larger than the previous session’s modest gain.
